Need to compile GGML for arm64 using cross compiler

[akapoor3518]

Hi,
Currently ggml auto detect hardware machine, since i am compiling at x86 machine its compiling for x86 machine. I would like to use cross compiler and compile for arm64 at x86 machine. Any suggestion here will be highly appreciable.
Thanks.
